Pulling the plates of an isolated charged capacitor apart:
A)increases the capacitance
B)increases the potential difference
C)does not affect the potential difference
D)decreases the potential difference
E)does not affect the capacitance

Question

Quizplus · Accepted Answer

Pulling the plates of an isolated charged capacitor apart increases the distance between the plates without changing the charge on them. According to the formula $C = \frac{Q}{V}$, where $C$ is the capacitance, $Q$ is the charge, and $V$ is the potential difference, keeping $Q$ constant while increasing the distance between the plates (which decreases $C$) must increase $V$, the potential difference.
